Many friends who have used a webcam may have such a confusion. Whenever the camera is used, there is a haze in the lens. What is the reason? Do not worry, in fact, this is only caused by heat, Xiao Bian today to tell you how waterproof network camera cooling.
The waterproof network camera is made of a series of 58 lamps connected in series. The heat generated by the lamp is transmitted through the positive and negative stages, and does not achieve a heat dissipation effect. Its packaging material is epoxy resin. , The working layer will appear broken for a period of time, resulting in the phenomenon of light failure, 3 months after the traditional infrared waterproof network camera can attenuate 30.
The formation of fog and frost is caused by the condensation of saturated steam in the air, which is condensed into frost and fog due to the strong and weak cold environment. During the working process of the infrared camera, especially the indoor camera often causes fog or frost on the protective window glass due to fog or water vapor. As a result, the camera cannot see the object directly, which directly affects the monitoring effect.
The solution to this problem is also different for each family. Increase the defrosting circuit, open vent holes, charge nitrogen, add fans, put desiccants and so on. The method is not the same, and the effect is certainly not the same. Some can solve the problem, and some still cannot solve the problem. However, from the most basic point of view, it is necessary to strictly control the cleaning of materials and try to prevent the presence of volatiles. For example, the PCB board cannot have residual flux, and the light-shielding rubber sleeve is made of high-quality silicone material.
In order to change the situation in which the infrared waterproof network camera has not had a long life due to poor heat dissipation, a new generation of infrared waterproof cameras has made innovations and improvements in lamps.
The new generation of infrared waterproof camera is a single lamp. Its one lamp is equivalent to 70-80 of the infrared lamp of the traditional camera. Its lamp is connected to the lamp through the lamp board (the lamp board is made of aluminum alloy). There is a heat sink, through the chip to connect the shell, so as to get the heat dissipation, its packaging material is the use of selenium rubber, because there is no broken layer, there will be no light failure, night vision effect is very good, life can reach 5 - For 10 years, no attenuation is visible to the naked eye within 2 years.
Therefore, the new generation of infrared waterproof network camera's heat dissipation is very good. If it is used, the shell is found to be hot to the touch, indicating that its heat energy has been dissipated. This is a good thing. Good heat dissipation also extends life.
A new generation of infrared waterproof network camera it is a very many points integrated, each dot matrix lamp can integrate 60-80 LED light crystals, the integrated volume is only the size of the nail, the finished product volume will not be too large. Because the dot matrix lamp is a highly integrated LED, it is much smaller than other products.
The main advantage of the small size is that it is easy to use. If an infrared light source with a combination of dozens of individual LEDs is to be installed on a high-speed dome camera, the effect is conceivable. The light angle of ordinary products is generally 7°-10°, so a beam of light like a flashlight is formed. The angle of our luminous body can reach 180°. The entire space can be evenly illuminated indoors. The single LED's optical output is 5mw-15mw, while a dot matrix lamp's optical output reaches 800mw-1000mw, and the size has only one penny coin size. This shows that the dot matrix light is clearer, brighter and more distant than the similar products on the market.
There are two possibilities: First, it may be because there is water vapor in the lens, the resulting blur! On the other hand, the Sensor used in the product is not very good. After being used for a long period of time, the picture quality becomes obscure. It may also be that the product is not very leak tight and there is water vapor on the lens. Second, the process of the machine itself, the quality of the network camera, but off, then it will be prone to lens money fog, rubber gaskets out of oil, the image is whitish, snow spots, noise and other phenomena, this is because of the aging of the sealed apron of.
